摘要
本文描述了一套基于小波理论进行心电信号处理的方案及其实现,即根据小波变换分解后,各个尺度上信号的特征采取相应的措施进行滤波或者R波检测。文章同时介绍了该方案的Matlab仿真结果。该方案不但具有简易性和运算的快速性,并在R波检测部分加入时域校正,达到良好的R波检测的正确率。
This article described a method and its implementation of ECG signal processing based on wavelet theory. In this method ECG signal is deconstructed by wavelet transform and made respective process of filtering and detection by the signal properties on different resolution. Its MATLAB emulation is also introduced. This is a creative method besides its simplicity and high speed, the accuracy of R - wave detection was also improved by time -domain correction.
